The results show that intense AE activities occur in a specimen during cyclic load-holding at different levels. With the increase in the number of cycles, the overall stability of the specimen gradually decreases. In the cyclic loading and unloading process, the specimen exhibits a Kaiser effect. As the number of cycles increases, more AE events occur in the unloading stage and a Felicity effect is manifest. The spatial distribution of AE events is related to the stress regime and structure of the specimen, crack propagation in the roadway exhibits directionality due to effects of the principal stress. High stress is conducive to microcrack initiation and propagation in the specimen, which accelerates damage accumulation and macrofracture formation in a rock mass. The research provides a reference for roadway support work and disaster prevention and control in deep mines.<\/jats:p>","DOI":"10.1371\/journal.pone.0286005","type":"journal-article","created":{"date-parts":[[2023,9,28]],"date-time":"2023-09-28T17:30:55Z","timestamp":1695922255000},"page":"e0286005","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":7,"title":["Spatio-temporal evolution of acoustic emission events and initiation of stress fields in the fracturing of rock mass around a roadway under cyclic high-stress loading"],"prefix":"10.1371","volume":"18","author":[{"given":"Gang","family":"Lei","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-1744-4631","authenticated-orcid":true,"given":"Dawei","family":"Wu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shengyan","family":"Zhu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"340","published-online":{"date-parts":[[2023,9,28]]},"reference":[{"issue":"1","key":"pone.0286005.ref001","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1016\/j.jrmge.2020.11.005","article-title":"Innovation and future of mining rock mechanics","volume":"13","author":"Manchao He","year":"2021","journal-title":"Journal of Rock Mechanics and Geotechnical Engineering"},{"key":"pone.0286005.ref002","first-page":"139","article-title":"Evolution models of the damage to the near-field rocks surrounding the drift under the disturbance caused by extraction of the longhole stope","author":"Dawei Wu","year":"2022","journal-title":"Engineering Failure Analysis"},{"key":"pone.0286005.ref003","first-page":"143","article-title":"Experimental and theoretical investigation of roadway fracture induced by static-blast loading using acoustic emission.","author":"Yingtao Si","year":"2023","journal-title":"Engineering Failure Analysis."},{"key":"pone.0286005.ref004","first-page":"163","article-title":"Experimental investigation and empirical model on damping properties of rock under multistage cyclic loading.","author":"Beibei Yang","year":"2022","journal-title":"Soil Dynamics and Earthquake Engineering."},{"issue":"5","key":"pone.0286005.ref005","doi-asserted-by":"crossref","first-page":"1531","DOI":"10.1016\/j.jrmge.2021.12.017","article-title":"A multifunctional rock testing system for rock failure analysis under different stress states: Development and application.","volume":"14","author":"Shucai Li","year":"2022","journal-title":"Journal of Rock Mechanics and Geotechnical Engineering"},{"key":"pone.0286005.ref006","first-page":"1531","article-title":"Fracture growth and acoustic emission response in natural coal-rock blocks with different stress, fracturing medium and injection rates","volume":"220","author":"Yulong Jiang","year":"2023","journal-title":"Journal of Petroleum Science and Engineering"},{"key":"pone.0286005.ref007","first-page":"312","article-title":"Mechanism of excavation-induced cracking of the protective layer of a rock bench in a large underground powerhouse under high tectonic stress","author":"Yuelin Xia","year":"2023","journal-title":"Engineering Geology"},{"key":"pone.0286005.ref008","article-title":"A rigid true triaxial apparatus for analyses of deformation and failure features of deep weak rock under excavation stress paths","author":"Xiating Feng","year":"2022","journal-title":"Journal of Rock Mechanics and Geotechnical Engineering"},{"key":"pone.0286005.ref009","first-page":"56","article-title":"Analysis of damage characteristics and energy evolution of salt rock under triaxial cyclic loading and unloading","author":"Hao Lin","year":"2023","journal-title":"Journal of Energy Storage"},{"issue":"17","key":"pone.0286005.ref010","volume":"13","author":"H.
